Rat or mouse? Pic included.

We have caught this is our outbuilding. Does anyone know if it's a rat or mouse? Thanks.

How big?

Mouse

Its a mouse

That’s a mouse.

I think rats usually have smaller ears in proportion to their heads but really you need to put something random like a banana next to it for scale.

It's hard to tell without any scale for size, possibly a baby rat.

It's definitely a mouse (i work with rats and mice so you can trust me!)

Looks like a mouse to me too!

Compare him with this @mgax

It's a mouse

Looks like a mouse - rats have small ears, mice have big floppy ones. Mice have tails longer than their body, rat tails tend to be fatter and the same size or smaller than their body.

A typical mouse will be about 10-15 cms body. A baby rat could be a similar size lengthways but they are a bit chunkier.

Mouse

Way too cute to be a rat. We had house mice and they were surprisingly big.

He's beautiful, whatever he is 🐭!

He was a cutie, was only tiny. Thanks everyone!

Need banana for context

Aww he’s lovely. I’d definitely say he’s a mouse. Will you be releasing him?

Sweet little mouse

Always quite difficult to tell without context, but, as a veteran of rats and mice🙄as we live in the country, A. it's a mouse, and B, it looks like its got big ears and big eyes and so I'd say field mouse rather than house mouse.
What sort of area are you in and what food/water is near by?
